Portable RK: A Portable Resource Kernel for Guaranteed and Enforced Timing Behavior
نویسندگان
چکیده
Portable RK is a portable implementation of a resource kernel, a resource-centric approach to build a real-time kernel that provides explicit timely, guaranteed and enforced access by applications to system resources [13]. Portable RK is designed to work with widely available operating systems with minimal changes. This facilitates experimentation in a familiar software environment and helps the faster deployment of research results. Execution in resource kernels is directly based on OS-enforced resource reservation [7]. As a result, an application can request the reservation of a certain amount of a resource, and the kernel can guarantee that the requested amount is exclusively available to that application. In this paper, we describe the design and implementation of Portable RK called Linux/RK that resides within the Linux operating system. The evaluation results show that Portable RK in the form of Linux/RK gives direct control over timely resource utilization by applications and that its overhead costs are small enough to be negligible.
